In which population genetics debunked Aryan Migration Theory and reinstated Aryan Invasion Theory

The Indus Valley people were a mix of Dravidians and Elamites.
Indo-Aryans were a mix of Europeans and Elamites.

There were two distinct groups.
1. Ancient North Indian: Mix of Indo-Aryans and Indus Valley people
2. Ancient South Indian: Mix of Dravidians and Indus Valley people

These two groups later mixed at a varying degree to form the present day Indians.

Interestingly, the major percentage (70-99%) of Indian genome belongs to Dravidians and Indus Valley people.

This again gives credence to the Aryan Invasion Theory where predominantly male Central Asian people, invaded and ruled over the local population spreading their culture and language. The female lineage(mtDNA haplogroup) is predominantly Dravidian and Elamite.
